Class
    Foam::functionObjects::writeLocalObjects

Description
    FunctionObject base class for managing a list of objects on behalf of the
    inheriting function object, on when those should be written to disk.

    FunctionObjects that inherit this class will receive the additional
    dictionary option \c objects which allows selecting which fields of the
    inherited function should be written to disk when \c write() is called.
    When \c objects is omitted, it will write all objects and when that list is
    empty, it will not write any of the inheriting function object's managed
    objects.

    Example of function object specification:
    \verbatim
    <functionObjectName>
    {
        ...
        objects     (obj1 obj2);
        ...
    }
    \endverbatim

Usage
    \table
        Property | Description                       | Required | Default value
        objects  | List of objects to be written     | no       | ".*"
    \endtable

    Note: Regular expressions can also be used in \c objects.
